The Marmora (or Marmara) Island (Gr: Προκόννησος) today Marmara Adasi, is a large island in the Sea of Marmara situated some 100 km south-west of Constantinople (Istanbul). Up until 1915, the island was almost exclusively Greek, inhabited by approximately 15,000 Greeks.

At midnight on the 6th and 7th of June 1915, Ottoman government officials began knocking on doors and advising Greeks that they were being deported to the Asia Minor interior. They were sent to places inhabited entirely by Muslims around Kermasti (Tr: Mustafakemalpaşa) situated some 60km to the interior of Asia Minor in the Bursa district, as well as Apollonias (Tr: Gölyazı) and Michalitch (Tr: Karacabey).
